Title： Cross Polarization Modulation based High OSNR Low Latent
Wavelength Converter with Hybrid Optical Amplifiers
Abstract
The extensive flow of “big data” every second has demanded faster
switching with lower noise content to maintain supremacy claimed by
companies. In this paper, an amplifier hybridization-based cross-port
wavelength converter has been proposed by utilizing Cross-Polarization
Modulation (XPoM). The implemented configuration uses the combination of
Semiconductor Optical Amplifier (SOA) and Erbium-Doped Fiber Amplifier (EDFA
) for creating a polarization-insensitive conversion with switching latency
of 0.124277 ns. The conversion efficiency has been evaluated using
parameters like injection current and port spacing. The Bit Error Rate (BER)
is monitored of injection current of SOA and Optical Signal-to-Noise Ratio
(OSNR) at a 10 Gbps data rate with existing Basic SOA based converters. The
BER of e-10 - e-15 and OSNR of 33.9 dB can be easily achieved by optimizing
the values of injection current and results prove to be better than basic
SOA conversions.
